Please report on all methods used in quantifying populations for this species (Q15) and provide a brief explanation (Q16), as well as an optional map (or series of maps) depicting the population structure (current and historical), if available (Q17). If only partial information on populations is available, it is highly recommended that assessors denote this information on the map(s) by indicating which populations are being assessed . Because only ONE file can be uploaded in Q17, if you have multiple maps we recommend pasting them into a single document (e.g., Word Doc [.docx], PDF). The maps may be rough sketches, drawn digitally, or taken as screenshots from publications.
